| 摘 要： | 利用新型荧光染料2-溴-4-氟苯乙烯-8-羟基喹啉锌(BFHQZn,(E)-2-(2-bromo-4-fluorostyryl)quinolato-Zinc)的电致发光(EL)特性,制备了非掺杂型的有机电致白光器件(WOLED)。器件的结构为ITO/CuPc(10nm)/NPBX(25 nm)/BFHQZn(18 nm)/NPBX(xnm)/BCP(10 nm)/Alq3((47-x)nm)/LiF(0.5 nm)/Al,当x为12时,得到了色度最好和效率最大的WOLED,最大电流效率为1.11 cd/A(at 10 V),最大的亮度为817 cd/m2(at 15 V),当驱动电压从7 V(启亮)升高到15 V(最高亮度)时,器件色坐标由(0.32,038)改变为(0.30,0.28)。
